Default Do you double clutch shift

I've been driving manual as a daily driver for most of 25 years but been driving auto for the last couple. I plan to be getting my manual transmission 370Z soon and want to fine-tune my driving (like heal-toe).

How many of you guys double clutch shift (up and down)? It's never been something that I've done much of. While it's not necessary, I've been reading that there are some advantages in smoothness of shift and wear and tear of the tranny.

Thoughts?

SRM eliminates the need for heel-toe.

Synchros in the transmission eliminate the need for double-clutching. Just slow down your shift if you find the synchros grinding. The 5th gear one is notoriously weak

If I downshift to fast from 6th to 5th my trans will bite (grind) a little.
I have to remember to slow down a bit on that shift.

I have heard the newer transmissions have updated syncro's they are supposedly "stronger" I am going to start preparing myself to drop
2K on a transmission at some point but for now I will just take it easy on that down shift.

I am a new owner and I am starting to wonder what I have gotten myself into.
This car doesn't seem to reliable. I guess time will tell. luckily its not my daily driver.

The Z is extremely reliable in my experience. I put over 100K miles on mine in 6 years. Plenty of other people have gone 200K+ miles without major work. It's got some quirks for sure - mostly because Nissan dropped the ball in a couple of areas. But there are well documented fixes. There are plenty of other vehicles out there with far worse issues than the Z

True. Thanks for talking me off the ledge! LOL. I am sure everything will work out.

I don’t think OP is talking about just heel-toe, but double clutching specifically. I don’t use the SRM, that much, but even when I do, I double clutch on the downshifts. In my mind, it spares the synchros a little. Much cheaper to replace a clutch than synchros.

Correct, I was referring to double clutch specifically not just heal-toe. I'll most likely be getting a base model so rev-matching isn't available. Either way, I read that double clutching will be easier on the syncros for both up-shift and down-shift.

You can shift perfectly smooth in the Z without double-clutching. But it takes some practice and skill to do so consistently. So while double-clutching is completely unnecessary, it would be a way to reduce wear on the synchros compared to poor shifting.

I have been driving cars with manual transmission for far longer than 25 years and I never had a need to double clutch in racing (autox and road course) and ESPECIALLY in daily driving. Good transmission fluid and good clutch hydraulic system are important. If a modern car like a 370Z needs a double-clutch, something is wrong with either the clutch system or the transmission itself.

Hell, I have driven an E36 M3 with a broken clevis on the clutch pedal mechanism (rendering the clutch hydraulic inoperative) without a grind. Planning the route to avoid as many intersections with a stop sign, a yield sign, and traffic lights was half the fun.

Just give it a little gas when you go through neutral as you downshift.

Double clutching is a thing of the past. The last time I had to double clutch. I was driving an 18 speed, split shift. Manuals in cars. No need for it. Even back in the 60's with T10's, top loaders, rock crushers, etc.
